Red is my weakest colour by far, now that I have 20 rings I should ascend some reds, but I really don’t know if they are worth the rings or using some LB 4*s would be as efficient but less costing. I usually attack with the pattern 3+2 or mono.
My ascended reds are: +20 C Gravemaker LB, +20 Garnet, +20 Vanda, +8 Yang Mai.
Ascended 4* reds: +20 C Boldtusk, +20 Wilbur, +20 Falcon, +20 Scarlett, Sumle, +20 Lancelot.
Red 5s: Russell, Marjana, Noor, Grazul, Reuben, Azlar, Khagan, Elena.
Red 4s: Ferant, Cillian, Aodhan, Eichelborg, Mack, Carol.
Other relevant ascended heroes for family bonus: Ludwig, MN, Pengi, Buddy.
Would you ascend some red 5s or LB some 4s instead?
Cillian and Ferant are just brilliant so I’d do them first! And as suggested Russell and Khagan would be great additions to your team. I tend to level up any hero that will add value to my team - like Almur, Wilbur, G Jackal. They are so valuable… then work around your team synergies! You have some great heroes to work on. I don’t have Aodhan but he would also be a good option.
